We never post fake jobs 
 
This isn't a trick. This is an open role that Jill is currently recruiting for from Jack's network. 
 
Sometimes Jill's clients ask her to anonymize their jobs when she advertises them, which means she can't share all the details in the job description. 
 
We appreciate this can make them look a bit suspect, but there isn't much we can do about it. 
 
Give Jack a spin! You could land this role. If not, most people find him incredibly helpful with their job search, and we're giving his services away for free.
